RESILIENT SHOE-HEEL.

I To all-whom it may concern.

Be it known that I, FRANCIS A. Nora in,

a citizen of the United States, residing at St. Paul, in the'county of Ramsey and State of Minnesota, have invented a new and useful Improvement in Resilient Shoe-Heels, of

which the following is a specification.

This invention relates to certain new and useful improvements in resilient shoe heels designed for permanent attachment to a shoe whereby a tight joint is effected so as to avoid the collection of dirt, moisture, and

the like, between the adjacent portions of the heel and shoe, and has for anebject to provide a heel of this type which 1s so for-medthat when the same is positioned upon the shoe, it is securely retained not only by means of the tacks, nails, or like devices employed, but also through the me 'dium of a suction-sealing action between the said shoe and heel.

Incertain respects this application may be regarded as a divisional application from that filed in the United States Patent Oflice by me July 17, 1916, Serial Number 109,654, and from which it difi'ers' principally through the fact, that, after having been secured in place, it affords an absolutely flattread surface which is to be desired.

Other and further objects and advantages of the invention will be hereinafter set forth and the novel features thereof defined by the appended claims.

In the drawings:

Figure 1 is an inverted plan of my improved lift;

Fig. 2 is a section taken on the line XX of Fig. 1 showing one form of nail receiving and retaining device employed;

Fig. 3 is a section of a modified form of lift taken, for example, on the line YY of Fig. 1;;

Fig. 4 is a section similar to that of Fig. 2, showing another form of nail receiving and retaining device;

Fig. 5 is an inverted. plan of a modified form of the invention;

Fig. 7 is a. side elevation of a detail of a shoe showing the invention applied thereto; and

Fig. 8 is a side elevation-of a detail of a shoe, partly in section, and showing the in-.

Like numerals of reference refer to like parts in the several figures of the drawing;

R-eferring to the drawing, the reference character A represents the improved cushioning device which is adapted for attachment to the usual heel 5 of a shoe, boot, 0r like form of foot apparehindicated by the character B.

It is well-known that cushion lifts are at present on the market which are provided. with concave upper and convex lower surfacesand that the purpose of such construcr is to increase the permanent attachment of'th'e lift to the heel of the shoe. These devices, however, have proven to be deficient in a number of ways and it is to overcome such defects that the present invention has been devised.

In the drawings, the resilient lift or heel A is provided with a central fiat face portion 6 of any yieldable material, such as rubber,

nary shoe heel, but on a reduced scale; while extending entirely around the edges of the portion 6 and angularly inclined therefrom is a flange 7 in the nature of a bevel of a thickness equal, or substantially so, to that of the base, the continuous free edge 8 of the flange or bevel lying in a single plane so that when the upper surface 9 of the lift formed as described is positioned upon the heel of the shoe, an absolutely air-tight joint. entirely around the lift results with the shoe heel, no cement whatsoever being required to attain this end. Consequently, when the fastening means, as nails, are driven through the base portion" of the lift and into the heel 1 of the shoe, the fiat base portionfi of the lift is forced into engagement with the heel and the edge 8 of the lift thus held firmhy in y place, the increased suction produce thus forining the device greatly enhancing pressure on t e outer edge. I In Fig. 6 is shown'a lift of a modified construction in that the body portien v is rounding ed e resulting dueto increasedmolded with an unin'lurrupl d i i on 10. lho conlinuous lroe ed oil which in a piano as in prrl crrod ."rn whereby wliun the lift is subjected lo prossure, the surface llatlrliud out and a norfect vacuum crcated llll'()ll {,ll )lll the on unper i'iurface oi llir lilfl' l'hus mate "saninn llu: llSllll'lRlg 1 urliou and u uirod.
